Thanks a lot for You help Tom.
Today, finaly I understand You suggestion about CXX and CC environment
variables.
I add file gcc.sh to /etc/profilr.d directory
and everything works fine. When I change export CC=/user/bin/gcc-X.Y.Z then
I change default compiler to X.Y.Z.
I try the same beafor but I don't discover so I must relogin. When I'm
logout and login again then everythings work ok.
Very very thanks for You help and patience.
Marek

Hi
I have installed gcc-4.0.1 in my mandriva2006 as default gcc compiler.
(its
a an rpm package)
I compile and install another gcc (4.2.0 or 3.4.6)
I try change symlinks. I try change alternatives. Everything looks Ok.
when I type gcc -- version I have 4.2.0. But when I try rebuild surces
by
rpmrebuild it's still use default gcc (4.0.1) and i have compilation
error
(incompatible with gcc 4.0.1).
When I uninstall rpm package with gcc-4.0.1 everything works fine,
rpmrebuild goes without any error. But when I install gcc-4.0.1 again,
then
it'is again default gcc and again can't rebuild my source.
My question is: How to change default gcc ?
Did you try my suggestion to set the CXX and CC environment variables
to the desired compilers? I use rpm build all the time and that seems
to work for me.
